UNITED STATES CARL G. TOENSE, OF CLEVELAND, OHIO.

VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 425,471, dated April15, 1890.

Application filed August 20, 1889. Serial No. 321,364. (No model.)

To all whom it may concern.-

Be it known that I, CARL G. TOENSE, of Cleveland, county of Ouyahoga,and State of Ohio, a citizen of the United States, have invented certainnew and usefullmprovcments in Riding-Cycles, of which the following is aspecification.

This invention relates to that class of vehicles that are propelled bythe rider; and the object of my invention is to provide a ridingcyclewhich is operated by means of hydraulic pressure, the rider moving upand down in the saddle in the same manner as he would when riding ahorse on a canter or gallop.

The invention consists in the combination, with a suitable frame andsteering and driving wheels, of suitable mechanism for rotating thedriving-wheels by means of hydraulic pressure. I

The invention also consistsin the construction and combination of partsand details, as.

will be fully described and set forth hereinafter, and finally pointedout in the claims.

In the accompanying drawings, Figure 1 is a side View of my improvedriding-cycle. Fig. 2 is a horizontal sectional view of the same Fig. 3is an enlarged detail longitudinal sectional view of the driving-cylinder, piston-rack, and clutch. Fig. 4 is a cross-sectional view of therack, showing an end view of the driving-cylinder. Fig. 5 is ahorizontal sectional view of the clutch. Fig. 6 is a verticallongitudinal sectional. View of a lower hydraulic cylinder and itspiston.

Similar letters of reference indicate'corresponding parts.

The frame A, the rear driving-wheel B, and the front steering-wheel Care of the usual construction, said front steering-wheel being mountedto turn, and being provided with a handle in the usual manner. On thebackbone A of the frame the hydraulic cylinder D is secured, which isshown in dotted lines,

and contains the piston D, secured to the piston-rod D projectingthrough the top of the cylinder, (also shown in dotted lines in Fig. 1.)On the upper end of the piston-rod D the saddle E is secured, and fromthe same two bars F project downward, the lower ends of which areconnected with the forked shanks (l of an angle-lever G, pivoted on anupwardly-projecting lug II of the bottom bars I of the frame. The otherupwardly-projecting arm G of said angle-lever G is connected by a rod Jwith the upwardly-projecting arm K of the angle-lever K, pivoted on thelug II of the bottom bar I of the frame. The forked shanks K of theangle-lever K are provided with notches in their end, through which across-rod Opasses, on the ends of which the vertical slidingdownwardly-projecting bars L are held, from the lower ends of which thetreadles M project laterally.

The cross-bar O is connected with the upper end of a piston-rod P,projecting upward from the piston P in a hydraulic cylinder Q,projecting downward from the bars I of the frame. The bars L areprovided with longitudinal slots L, through which guide-pins L projectlaterally from the sides of the cylinder Q.

The lower end of the upper hydraulic cylinder D is connected by a pipe Rwith a horizontal pipe R, the opposite end of which is connected with ahydraulic driving-cylinder S, secured horizontally on one of the sidebars of the frame. The lower end of the bottom hydraulic cylinder Q isconnected by a pipe T with the horizontal pipe T, the other end of whichis connected with the driving-cylinder S, held horizontally on that sideof the frame opposite the one on which the cylinder S is held. Thecylinders S and S each con tain a piston U, with which a rack-bar U isconnected, projecting from the open rear end of said cylinder, saidrack-bar being suitably guided to reciprocate horizontally. The rackbarsU each engage a cog-wheel V, formed on the rim of a clutching-wheel V,having tapering recesses V in which rollers IV are arranged, that canimpinge on the rim of a fixed clutching-pulley a, keyed on the axle (Zof the rear or driving wheel 0.

The operation is as follows: When the riderv mounts the cycle and restshis weight upon the seat E, said seat will be forced downward, andthereby the liquid in the upper hydraulic cylinder D is'force'd throughthe pipes R B into the cylinder 8 and forces the piston in said cylinderin the direction of the arrow on, Fig. 3, whereby the cog-wheel V isrotated in the direction of the arrow 34 and by means of theintermediate clutching-rollers \V rotates the pulley a aXled, anddriving-wheel B in the direction of the arrow 00 thus moving the vehicleforward. As, the seat descends the bars F also descend, and by means ofthe angle-levers G and K pull upward the bars L,

' whereby the piston P in the bottom hydraulic cylinder Q is raised, andthe piston U in the cylinder S is moved in the inverse direction of thearrow 00', and the corresponding cog- Wheel V rotated in the inversedirection of the arrow och-Without, however, acting on the axle d. Whenthe seat has arrived at its lowest position, the rider bears down on thetreadles M, at the same time raising himself in the seat, whereby thepiston of the lower hydraulic cylinderis forced downward an d the liquidforced from said lower hydraulic cylinder into the driving-cylinder Swhereby the piston in said driving-cylinder is moved in the direction ofthe arrow x and the wheel B rotated in the direction of the arrow 00 Atthe same time the seat is raised, the upward moti on being imparted tothe same from the bars L by the angle-levers G K and the connecting-rodJ, and thus the piston and rack of the cylinderS are moved in theinverse direction of the arrow as, and so on, for the reason that theliquid is drawn by suction out of the cylinder S, and the pressure ofthe exterior air, acting on the piston U, moves the same in the inversedirection of the arrow 00, as stated above. The driving-wheel is thusacted upon alternately by the two driving-cylinders, one acting when theseat descends and the other when the treadles are forced down.

The liquid used in the cylinders is either glycerine, oil, water,alcohol, or a, mixture of either of these, as desired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A riding-cycle constructed with two hydraulic-pressure cylinders connected with the seat and treadles,respectively, and mechanism, substantially as described, for transmitting motion from said hydraulic-pressure cylinders to the driving-wheel,substantially as set forth.

2. In a riding-cycle, the combination, with a frame and wheels, of twohydraulic-pressure cylinders connected with the seat and treadles,respectively, levers and rods connecting the pistons of said twopressure-cylinders, and mechanism, substantiallyas shown and described,for transmitting motion from said pressure-cylinders to thedriving-wheel,

wheels, of a driving-cylinder on each side'of the frame, a piston ineach driving-cylinder,-

a rack-bar on each piston and cog-wheels engaging with each rackfbar,clutches for transmitting motion from said cog-wheels to thedriving-wheel shaft, two hydraulic-pressure cylinders on the frame ofthe machine, one of said pressure-cylinders being connected with onedriving-cylinder and the other pressure-cylinder with the otherdriving-cylinder,

'a seat connected with the piston-rod of one pressure-cylinder, treadlesconnected with the piston-rod of the other pressure-cylinder, andangle-levers and rods connecting the pistonrods of the twopressure-cylinders, substantially as set forth.

In testimony that I claim the foregoing asmy invention I have signed myname in presence of two subscribing witnesses.

CARL G. TOENSE.
